Luckily speech (math, algorithms, etc) are protected in the US and many other developed countries so even when the PGP code was considered a 'munition', at the end of the day they couldn't/wouldn't bother charging the creator of PGP with exporting munitions[0]. Currently the same shame 'investigation' is occurring with 3D blueprints to print firearms[1] but it's almost certainly going to fall under protected speech as well. The difference between the two is that encrypted data can also be considered speech while the actual manufacture/printing of a gun can be regulated. The big IF at least in the US IMHO is whether the government can force private companies to not offer E2EE but there is 0% chance that encryption in general could be criminalized. i.e it will always be legal to send PGP encrypted text through WhatsApp or a private Chanel (self-hosting IRC, email, etc.) So the hypothetical law you proposed wouldn't be legal in the US. On the other hand, if major companies are forced to break their E2EE, it will make the rest of us stand out like a really sore thumb.
